Abstract:

Increasing utility load for a particular Permanent Magnet Brushless DC Motor (PMBLDC), it suffers from getting more input from the source so certain considerations should be made to avoid this. One among the consideration is about the design of the Motor. It should be modified in a form having better efficiency and constant Torque so that it can reducing the input consumption resulting in energy saving. PMBLDC drives are becoming widely used in various consumers and industrial applications such as Servo motor drives, Home Appliances, Computer Peripherals and Automotive Applications because of its silent operation, compact size, Reliability and Low Maintenance. In our paper these features can be enhanced by using energy recovery scheme. The main aim is to design a Simulation model of Permanent Magnet Brushless Dc motor and to increase it usage. To promote energy efficient, we employ C-dump technology. The principle behind this technology is that the capacitor is added to the circuit to store the demagnetized energy of the stator windings. Also the stator winding is excited in a way to produce constant torque. Hence the PMBLDC drive with increased efficiency and constant torque achieves its greater usage.
